An updated openais package that fixes various bugs is now available for Red HatEnterprise Linux 5.

The Application Interface Specification (AIS) is an API and a set of policiesfor developing applications that maintain services during faults. The OpenAISStandards Based Cluster Framework is an OSI-certified implementation of theService Availability Forum AIS. The openais package contains the openaisexecutable, OpenAIS service handlers, default configuration files and an initscript.

This update fixes for the following bugs:

* When a system limit for semaphores or shared memory was exceeded on SysV, theopenais client sometimes went into a loop. With this update, the openais clienthandles the situation properly, and no longer enters an infinite loop wheneither of these limits is exceeded. (BZ#694180)

* When the OpenAIS limit for open files was exceeded, the openais executableterminated unexpectedly. With this update, if the limit is reached, thepublished server listening socket is withdrawn and the connection closes withoutcausing any crashes. (BZ#694181)

* Previously, if a token was lost in the recovery state, the openais executablesometimes accepted a commit token with old ring ID information. This resulted inan unexpected termination. This bug has been fixed and lost tokens are nowhandled properly. (BZ#694182).

* When the ring ID file for a processor was less then 8 bytes long, totemsrpterminated unexpectedly. Now, OpenAIS always creates fresh ring ID file datawhen an incorrect number of bytes are read from the ring ID. (BZ#694183)

All users of openais are advised to upgrade to this updated package, which fixesthese bugs.
